by Zhongyang He, Jonathan M. Heess, Travis Young, Zhen Lei The COVID-19 pandemic introduced imminent and lasting impacts on the opioid crisis in the U.S., including a significant increase in opioid overdose and deaths and in use of telehealth in treatment. What lessons can we learn from the treatment transition during the pandemic that could help tackle the opioid crisis when future pandemics strike? In this paper, we conducted a phone survey with opioid treatment facilities in Pennsylvania to examine the COVID-19’s impacts on treatment facilities and individuals with opioid use disorder during the first year of the pandemic. We separated the lockdown period (Mid-March through Mid-May, 2020) from the reopening period that followed, and urban areas from rural areas, to explore temporal evolution and rural-urban variations in the COVID-19’s impacts. We found rural-urban heterogeneity in facilities’ adoption of telehealth in treatment and in challenges and risk factors faced by their clients during the lockdown period. During the reopening, telehealth was adopted by most facilities, and telehealth-related challenges became less salient; however, both rural and urban facilities reported higher relapse risks faced by their clients, citing factors more likely to be at clients’ end and related to socioeconomic stressors and mental health. Our results highlight the vitality of addressing socioeconomic and mental health challenges faced by individuals with OUD, via government policies and community interventions, when future pandemics strike. The findings also indicate the importance of maintaining facilities’ financial well-being to provide treatment services.

Abstract Background Nirmatrelvir/ritonavir (NM/r) is a safe and effective oral antiviral therapeutic used for treatment of mild-to-moderate COVID-19. Case reports described a clinical rebound syndrome whereby individuals experience a relapse of symptoms shortly after completing successful treatment. There is a lack of information on frequency of COVID-19 rebound after NM/r in routine clinical care, contributing factors, and clinical outcomes. Methods We reviewed electronic medical records to verify COVID-19 diagnosis, symptoms, and treatment with NM/r from January-June 2022. We defined COVID-19 clinical rebound as clear improvement in symptoms followed by recurrence or worsening of symptoms within 30 days of a five-day course of NM/r. Results We studied 268 adults with median age 57 (IQR 47, 68), 80% White race, 85% non-Hispanic ethnicity, 55% female, 80% vaccinated and boosted against SARS-CoV-2, and 68% with any co-morbidity. Sixteen (6.0%) of studied patients were determined to have COVID-19 clinical rebound. The median time from starting NM/r to rebound was 11 days (IQR 9, 13). Notable demographic and clinical factors with higher proportion (not statistically significant) among COVID-19 rebound patients were female sex (75% rebound vs. 54.5% no rebound), Black race (12.5% rebound vs. 4.9% no rebound), presence of at least one co-morbidity (81.3% rebound vs. 67.5% no rebound), and lack of prior SARS-CoV-2 infection (100% rebound vs. 92.9% no rebound). Only one patient (6.25%) was hospitalized after COVID-19 rebound. Conclusions COVID-19 clinical rebound after treatment with NM/r is mild with favorable outcomes and more common than previously reported from real-world clinical care studies. …

Abstract Purpose Respiratory syncytial virus (RSV) infection is a major cause of childhood hospitalization. The COVID-19 pandemic has disrupted the usual seasonal pattern of RSV, resulting in high activity during the off-season. This study aims to evaluate the effects of the pandemic on the severity of RSV infections. Methods Data from 11,915 children hospitalized due to RSV infection between 2016 and 2022 were analyzed. The hospitalized patients were categorized into two groups, from January 2016 to February 2020 (PreCoV19 group) and from March 2020 to December 2022 (CoV19 group). The hospitalization duration, intensive care unit (ICU) admissions, length of stay at ICU, mechanical ventilation requirement and duration, Elixhauser comorbidity index scores, and in-hospital mortality were analyzed. Results Children in the PreCoV19 group had a mean age of 0.4 ± 0.7, whereas those in the CoV19 group had a mean age of 0.6 ± 1.0 years. Children during the pandemic had significantly shorter hospital stays (4.3 ± 2.6 days) compared to children of the pre-pandemic period (4.9 ± 3.3 days). Although ICU admission rates did not change, the duration of ICU stays decreased in the CoV19 group. Moreover, the in-hospital mortality did not differ between the groups. A multivariable analysis showed that younger age, regardless of the pandemic period, was associated with prolonged hospital stays, higher ICU admission rates, and an increased requirement for mechanical ventilation. Conclusion Our findings highlight significant changes of the clinical characteristics of RSV infections during the pandemic, with implications for clinical management and public health strategies. …

IntroductionPost-COVID-19 condition (post COVID, also known as long COVID) is a global public health issue estimated to affect over 100 million people. Common symptoms include fatigue, dyspnoea and cognitive dysfunction (‘brain fog’). Over time, these symptoms have an adverse effect on mental health, physical activity and quality of life (QoL). The condition requires innovative and feasible treatment approaches that can be effective and self-managed. Physical activity is essential for good health; however, aerobic exercise or weightlifting may not be suitable for post COVID patients who experience fatigue or breathlessness. The benefits of yoga include improved flexibility, mobility, body strength and balance. It is also shown to reduce symptoms of fatigue and improve breathing efficiency, mental health and QoL. This study protocol describes the rationale and methods for a randomised controlled trial (RCT) of a yoga-based intervention designed for adults with post COVID. Methods and analysisA two-group, parallel, RCT with blinded follow-up assessments. Participants will be randomised with a 1:1 allocation to either a 12-week yoga-based intervention or a 12-week health promotion (active comparison) intervention. In total, 88 participants aged 30–65 years will be recruited and randomised. The primary outcome is health-related QoL (36-item Short-Form). Secondary outcomes are dyspnoea, fatigue, sleep quality, cognitive functions, mental fatigue, depression, anxiety, physical activity, demographic data and physical health measures. Data will be analysed as intention-to-treat basis, using linear mixed modelling. All assessments are conducted at Karolinska Institutet in Stockholm, Sweden. The yoga-based intervention will take place at a yoga studio centrally located in Stockholm city. Ethics and disseminationThe study is approved by the Swedish Ethical Review Authority, reference number 2023/06518-01. All participants must sign written informed consent before enrolment and are free to withdraw from the study at any point. Key results will be available through research articles and seminars.

Abstract Background Hybrid immunity provides better protection against COVID-19 than vaccination or prior natural infection alone. It induces high magnitude and broadly cross-reactive neutralising anti-Spike IgG antibodies. However, it is not clear how long these potent antibodies last, especially in the context of adenovirus-based COVID-19 vaccines. Methods We conducted a longitudinal cohort study and enrolled 20 adults who had received an adenovirus-based COVID-19 vaccine before a laboratory-confirmed SARS-CoV-2 infection. We followed up the study participants for 390 days post the initial breakthrough infection. We assessed the longevity and cross-reactive breadth of serum antibodies against SARS-CoV-2 variants of concern (VOCs), including Omicron. Results The binding anti-Spike IgG antibodies remained within the reported putative levels for at least 360 days and were cross-neutralising against Beta, Gamma, Delta, and Omicron. During the follow up period, a median of one SARS-CoV-2 re-infection event was observed across the cohort, but none resulted in severe COVID-19. Moreover, the re-exposure events were associated with augmented anti-Spike and anti-RBD IgG antibody titres. Conclusions This study confirms that hybrid immunity provides durable broadly cross-reactive antibody immunity against SARS-CoV-2 variants of concern for at least a year (360 days), and that it is further augment by SARS-CoV-2 re-exposure. …

Abstract Background Antiviral drugs show significant efficacy in non-severe COVID-19 cases, yet there remains a subset of moderate COVID-19 patients whose pneumonia continues to progress post a complete course of treatment. Plasma-activated water (PAW) possesses anti-SARS-CoV-2 properties. To explore the potential of PAW in improving pneumonia in COVID-19 patients following antiviral treatment failure, we conducted this study. Methods This was a randomized, controlled trial. Moderate COVID-19 patients with antiviral treatment failure were randomly assigned to the experimental group or the control group. They inhaled nebulized PAW or saline respectively. This was done twice daily for four consecutive days. We assessed improvement in chest CT on day 5, the rate of symptom resolution within 10 days, and safety. Results A total of 23 participants were included, with 11 receiving PAW and 12 receiving saline. The baseline characteristics of both groups were comparable. The experimental group showed a higher improvement rate in chest CT on day 5 (81.8% vs. 33.3%, p = 0.036). The cumulative disappearance rate of cough within 10 days was higher in the experimental group. Within 28 days, 4 patients in each group progressed to severe illness, and no patients died. No adverse reactions were reported from inhaling nebulized PAW. Conclusion This pilot trial preliminarily confirmed that nebulized inhalation of PAW can alleviate pneumonia in moderate COVID-19 patients with antiviral treatment failure, with no adverse reactions observed. This still needs to be verified by large-scale studies. Trial registration Chinese Clinical Trial Registry; No.: ChiCTR2300078706 (retrospectively registered, 12/15/2023); URL: www.chictr.org.cn. …

ObjectiveLiver function test (LFT) abnormalities are higher in patients with severe COVID-19. Most of the studies on this theme were conducted in foreign nations, and the association with LFT abnormalities was not sufficiently addressed in the study areas. Therefore, the current study aimed to investigate the effects of COVID-19 infection on liver function of patients. SettingA facility-based comparative cross-sectional study was carried out from 10 April to 15 June 2022, among COVID-19 infected individuals admitted in Eka Kotebe General Hospital and Saint Petrous Specialized Hospitals, Addis Ababa, 2022. ParticipantsA total of 284 confirmed COVID-19-positive and COVID-19-negative controls matched by gender and age were included in the present study. ResultsAmong SARS-COV-2 positive groups, 63 (44.4%) had one or more LFT abnormalities. The most common elevated level of the LFTs among patients with COVID-19 were gamma-glutamyl transferase (GGT) 50 (35.2%), while the most common lowered level was albumin 58 (40.8%). The mean values of aspartate aminotransferase (AST) (35.4±26.9 vs 22.9±12.6, p

ObjectivesWhile older adults showed higher mortality during COVID-19 pandemic, protective behaviours (knowledge regarding coping with COVID-19 symptoms and preventive behaviours) were highlighted to be important to prevent the spread of infection. This study aimed to identify individual and community-level variables influencing deficient knowledge regarding coping with COVID-19 and not-practicing COVID-19 of older adults during the pandemic. DesignThis is a secondary analysis of a cross-sectional study using the 2020 Korea Community Health Survey (KCHS). Setting255 community public health centres nationwide, South Korea. Methods and analysisUsing 2020 KCHS data, multilevel logistic regression analysis was conducted on 55 005 adults aged 65 years or older. ResultsOlder adults who reside alone, as opposed to with their spouse and who lack the support of another individual exhibited insufficient COVID-19 coping-related knowledge (OR: 1.142, p

ObjectivesTo appraise the quality of clinical practice guidelines (CPGs) and expert consensus statements on rehabilitation for patients with COVID-19, summarise recommendations of rehabilitation assessments and interventions and evaluate the heterogeneity of the recommendations. DesignSystematic review. Data sourcesPubMed and Embase databases and five online guideline repositories: The National Guideline Clearinghouse, Guidelines International Network, Scottish Intercollegiate Guidelines Network, National Institute for Health and Clinical Excellence and WHO were searched from their inception to August 2024. In addition, we reviewed reference lists of eligible citations and searched the grey literature on the relevant websites. Eligibility criteria for selecting studiesWe included CPGs and expert consensus statements which provided information about rehabilitation of patients with COVID-19. To be eligible, the CPGs and expert consensus statements were issued in English by a nationally or internationally recognised government authority, medical/academic society or organisation. If there were multiple versions of the guidelines, we included the latest one. The translations, interpretations and abstracts of guidelines were excluded. Data extraction and synthesisAll recommendations on rehabilitation assessments and interventions for COVID-19 were extracted and summarised. Two reviewers independently evaluated the methodological quality with the Appraisal of Guidelines for Research and Evaluation (AGREE) II instrument, and two other reviewers assessed the reporting quality using the Reporting Items for Practice Guidelines in Healthcare (RIGHT) statement of included CPGs and expert consensus statements. We used the Measurement Scale of Rate of Agreement to evaluate the heterogeneity of the recommendations in different CPGs and expert consensus statements. ResultsA total of 31 CPGs and expert consensus statements were included. 14 guidelines provided recommendations for rehabilitation assessments. At the early, development, critical and recovery stages of COVID-19, the most frequently recommended were exercise therapy (25.8%, 35.5%, 25.8% and 58.1%, respectively). According to AGREE II, 17 included guidelines were assessed as low methodological quality (35%–56%), 10 guidelines were rated as moderate quality (46%– 62%) and four had high quality (69%–79%). Among 31 eligible guidelines, the reporting rate of 22 items in the RIGHT checklist ranged from 10% to 100%. The included guidelines were consistent with the reference guidelines (80%–100%). Only one guideline existed minor (60%–80%) disagreements in respiratory muscle training relative to the reference guideline. ConclusionsRehabilitation assessments and interventions should be implemented consistently throughout the entire process of COVID-19. The recommendations should be tailored to each stage of COVID-19. The methodological and reporting qualities of several guidelines remain suboptimal. Therefore, developers should adhere strictly to the AGREE II standard and RIGHT checklist to formulate and publish CPGs and expert consensus statements with high quality.

ObjectivesThis study addressed two research questions: What factors do doctors in training describe as influencing their choices to apply (or not apply) for specialty training during their Foundation Year 2? Which of these factors are specific to the context of the COVID-19 pandemic, and the unique experiences of the cohort of doctors who qualified early during the pandemic? DesignSequential explanatory mixed methods study: Quantitative survey. Qualitative semistructured interviews. Quantitative data were analysed with logistic regression. Qualitative data were analysed using reflexive thematic analysis. SettingUK-wide. ParticipantsJunior doctors who graduated medical school in 2020. Survey: 320 participants (22% of those contacted). 68% (n=219) were female, 60% (n=192) under 25 and 35% (n=112) 25–30. 72% (n=230) were white, 18% (n=58) Asian and 3% (n=10) black. Interviews: 20 participants, 10 had applied for specialty training, 10 had not. ResultsA minority of respondents had applied for specialty training to start in 2022 (114, 36%). While burnout varied, with 15% indicating high burnout, this was not associated with the decision to apply. This decision was predicted by having taken time off due to work-related stress. Those who had not taken time off were 2.4 times more likely to have applied for specialty training (OR=2.43, 95% CI 1.20 to 5.34). Interviews found reasons for not applying included wanting to ‘step off the treadmill’ of training; perceptions of training pathways as inflexible, impacting well-being; and disillusionment with the community and vocation of healthcare, based, in part, on their experiences working through COVID-19. ConclusionsParticipants infrequently cited factors specific to the pandemic had impacted their decision-making but spoke more broadly about challenges associated with increasing pressure on the health service and an eroded sense of vocation and community. …

Abstract Background Hospitals should prepare for emerging diseases and protect healthcare workers (HCWs) from work-related infection. This study aims to assess public hospital preparedness for the coronavirus disease 2019 (COVID-19) a year after the Myanmar government began implementing COVID-19 prevention measures, and to identify factors associated with work-related COVID-19 infection among HCWs in Myanmar. Methods In January 2021, data were collected from 101 hospitals and 706 HCWs who had COVID-19 in Myanmar in 2020. Data from the hospitals included basic information, the status of infection prevention and control (IPC), the preparedness for COVID-19 (guidelines, checklists, fever screening, patient pathway, and training), handwashing facilities, and availability of personal protective equipment (PPE). Data of COVID-19 infected HCWs included age, occupation, workplace, severity and source of COVID-19 infection, knowledge and practice of handwashing, and working environment. Chi-square test was performed to compare the preparedness for COVID-19 among three hospital levels (primary, secondary and tertiary levels). Logistic regression analysis was performed to identify the associated factors of work-related infection of HCWs. Results The total number of beds, HCWs, and COVID-19 patients in 2020 at the 101 hospitals was 12,888, 14,421, and 19,835, respectively. The availability of PPE was high in hospitals at all levels. Approximately 80% of hospitals had functional status of IPC, set up fever screening and patient pathway, and provided training on IPC and COVID-19. However, only 39.6% of hospitals had developed COVID-19 guidelines and 55.4% had developed checklists. The percentage of hospitals that prepared each measurement was lowest at the primary level. The factors associated with work-related COVID-19 among HCWs were being 30–39 years old, working as a doctor, working at isolation wards, having disinfection technique training, and having enough PPE at the workplace. Conclusion The preparedness for COVID-19 at public hospitals in Myanmar in January 2021 was insufficient, especially in the availability of the guidelines and checklists and at primary hospitals. A support system for hospital pandemic preparedness and monitoring of IPC implementation is needed. The government should prepare for emerging diseases and provide appropriate and adequate PPE and additional training to all HCWs, especially HCWs who work for isolation wards. …

by Karen Jennings, Martina Lembani, Anneke C. Hesseling, Nyameka Mbula, Erika Mohr-Holland, Vanessa Mudaly, Mariette Smith, Muhammad Osman, Sue-Ann Meehan Background Coronavirus disease (COVID-19) negatively impacted tuberculosis (TB) programs which were already struggling to meet End-TB targets globally. We aimed to quantify and compare diagnosis, treatment initiation, treatment success, and losses along this TB care cascade for drug-susceptible TB in Cape Town, South Africa, prior to and during COVID-19. Methods This observational study used routine TB data within two predefined cohorts: pre-COVID-19 (1 October 2018–30 September 2019) and during-COVID-19 (1 April 2020–31 March 2021). The numbers of people diagnosed, treated for TB and successfully treated were received from the Western Cape Provincial Health Data Centre. Pre and post treatment loss to follow up and cascade success rates (proportion of individuals diagnosed with an outcome of treatment success) were calculated and compared across cohorts, disaggregated by sex, age, HIV status, TB treatment history and mode of diagnosis. Results There were 27,481 and 19,800 individuals diagnosed with drug-susceptible TB in the pre- and during-COVID-19 cohorts respectively, a relative reduction of 28% (95% CI [27.4% - 28.5%]). Initial loss to follow up increased from 13.4% to 15.2% (p…

Methods The study utilized existing hospital admission data from the Thai Health Information Portal (THIP) database, covering the period from 2017 to 2022. We categorized WHO’s three disease groups: poverty-related, noncommunicable, and injury groups using the International Classification of Diseases (ICD)—10 of initial admission of patients, and we analyzed three major outcomes: prolonged (≥ 90th percentile) length of stay (LOS), hospital mortality, and readmission pre-, during, and post-COVID-19 pandemic peak. Relative weight (RW) of hospital reimbursements was used as a surrogate measure of the severity of the diseases. Results The average prolonged LOS of patients with poverty disease pre-, during, and post-COVID-19 pandemic peak were 7.1%, 10.8%, 9.05%, respectively. Respective hospital mortality rates were 5.02%, 6.22%, 6.05% and readmission were 6.98/1,000, 6.16/1,000, 5.43/1,000, respectively. For non-communicable diseases, the respective proportions in the prolonged LOS were 9.0%, 9.12%, and 7.58%, with respective hospital mortality being 10.65%, 8.86%, 6.62%, and readmissions were 17.79/1,000, 13.94/1,000, 13.19/1,000, respectively. The respective prolonged LOS for injuries were 8.75%, 8.55%, 8.25%. Meanwhile, respective hospital mortality were 4.95%, 4.05%, 3.20%, and readmissions were 1.99/1,000, 1.60/1,000, 1.48/1,000, respectively. The RW analysis reveals diverse impacts on resource utilization and costs. Most poverty-related and noncommunicable diseases indicate increased resource requirements and associated costs, except for HIV/AIDS and diabetes mellitus, showing mixed trends. In injuries, road traffic accidents consistently decrease resource needs and costs, but suicide cases show mixed trends. Conclusions COVID-19 had a more serious impact, especially prolonged LOS and hospital mortality for poverty-related diseases more than noncommunicable diseases and injuries. …

Abstract Background Understanding antibody responses to SARS-CoV-2 vaccination is crucial for refining COVID-19 immunization strategies. Generation of mucosal immune responses, including mucosal IgA, could be of potential benefit to vaccine efficacy, yet limited evidence exists regarding the production of mucosal antibodies following the administration of current mRNA vaccines to young children.Methods We measured the levels of antibodies against SARS-CoV-2 from a cohort of children under 5 years of age (N=24) undergoing SARS-CoV-2 mRNA vaccination (serially collected, matched serum and saliva samples) or in a convenience sample of children under 5 years of age presenting to pediatric emergency department (nasal swabs, N=103). Further, we assessed salivary and nasal samples for the ability to induce SARS-CoV-2 spike-mediated neutrophil extracellular traps (NET) formation.Results Longitudinal analysis of post-vaccine responses in saliva revealed the induction of SARS-CoV-2 specific IgG but not IgA. Similarly, SARS-CoV-2 specific IgA was only observed in nasal samples obtained from previously infected children with or without vaccination, but not in vaccinated children without a history of infection. In addition, oronasopharyngeal samples obtained from children with prior infection were able to trigger enhanced spike-mediated NET formation, and IgA played a key role in driving this process.Conclusions Despite the induction of specific IgG in the oronasal mucosa, current intramuscular vaccines have limited ability to generate mucosal IgA in young children. These results confirm the independence of mucosal IgA responses from systemic humoral responses following mRNA vaccination and suggest potential future vaccination strategies for enhancing mucosal protection in this young age group.

by Julia Smith, Muhammad Haaris Tiwana, Alice Murage, Hasina Samji, Rosemary Morgan, Jorge Andres Delgado-Ron While there is growing literature on experiences of healthcare workers and those providing unpaid care during COVID-19, little research considers the relationships between paid and unpaid care burdens and contributions. We administered a moral distress survey to healthcare workers in Canada, in 2022, collecting data on both paid and unpaid care. There were no significant differences in the proportion of participants providing unpaid care by gender, with both genders equally affected by certain responsibilities such as reduced contact with family/loved ones. However, men were significantly more distressed about specific unpaid care responsibilities. Unpaid care was not significantly associated with differences in intention to leave work. At work, women were significantly more concerned about patients unable to see family, while men were distressed by others mistreating COVID patients. This study enhances understanding of paid and unpaid care relationships, particularly during crises, and proposes an innovative method for assessing unpaid care burdens.

Abstract Background The mortality risk of co-infections/secondary infections (CoI/ScI) is under-reported in patients with non-critical COVID-19, leading to the under-management of CoI/ScI and publication bias in the medical literature. We aimed to investigate the association between CoI/ScI and mortality in patients hospitalised with mild-to-severe COVID-19. Methods We conducted a retrospective cohort study at a COVID-19 treatment hospital in Vietnam and collected all eligible medical records, with CoI/ScI status as the exposure (non-CoI/ScI and CoI/ScI, with the latter including nature of pathogen [bacterial, fungal, or bacterial + fungal] and multidrug-resistance pathogen [no MDRp or ≥ 1 MDRp]). The outcome was all-cause mortality, defined as in-hospital death by all causes or being discharged under critical illness. We used time-dependent analysis to report rates of mortality with 95% confidence intervals (95% CI, Poisson regression) and hazard ratios (HR) with 95% CI (Cox proportional hazards regression with Holm’s method for multiplicity control). Results We followed 1466 patients (median age 61, 56.4% being female) for a median of 9 days. We recorded 387 (26.4%) deaths (95/144 [66.0%] in the CoI/ScI group and 292/1322 [22.1%] in the non-CoI/ScI group). Adjusted mortality rates (per 100 person-days) of the CoI/ScI (6.4, 95% CI 5.3 to 7.8), including bacterial (8.0, 95% CI 7.2 to 8.9), no MDRp (5.9, 95% CI 4.8 to 7.4), and ≥ 1 MDRp (9.0, 95% CI 8.2 to 10.0) groups were higher than that of the non-CoI/ScI group (2.0, 95% CI 1.8 to 2.2). These corresponded to higher risks of mortality in the overall CoI/ScI (HR 3.27, 95% CI 2.58 to 4.13, adjusted p 

Abstract Background While COVID-19 has been controlled and deaths have decreased, the long-term consequences of COVID-19 remain a challenge we face today. This study was conducted to determine the relationship between the apoptosis of lymphocyte cells with DNA damage and oxidative stress and the therapeutic and clinical outcomes of elderly patients with COVID-19. Methods This study was conducted from April 2020 to May 2021 (the period of severe attacks of the epidemic peak of COVID-19) and September 2022 (the post-COVID-19 period). The study groups included elderly patients with COVID-19 hospitalized in the ICU and normal wards of the hospital as well as elderly patients with influenza. A polymerase chain reaction was used to check the validity of the studied diseases. The Annexin V/Propidium Iodide method was used to evaluate the level of apoptosis. Genotoxic effects and DNA damage were assessed by the comet assay method. Total antioxidant status (TAS), total oxidant status (TOS), and myeloperoxidase activity (MPO) were measured by photometric methods. Results The highest level of apoptosis in peripheral blood lymphocytes and the highest level of DNA damage were observed at both times in the intubated-ICU and non-intubated-ICU groups. In all groups, there was a significant increase in peripheral blood lymphocyte apoptosis levels and DNA damage levels compared to the healthy control group (p 

Abstract Background Pregnancy is a critical time for women, making them more susceptible to infectious diseases like COVID-19. This study aims to determine the immunogenicity of COVID-19 in pregnant women who have been infected compared to those who have received the inactive COVID-19 vaccine. Materials and methods In this retrospective cohort study, pregnant women who received the inactivated COVID-19 vaccine (Sinopharm) and those with a history of COVID-19 infection during pregnancy were studied. Participants who had experienced stillbirth, received different COVID-19 vaccines, or had intrauterine fetal death were excluded from the study. Overall, the study included 140 participants. The participants were divided into two groups of 70 participants - pregnant women who received the Sinopharm vaccine and pregnant women who had COVID-19 infection during pregnancy. Before delivery, blood samples were collected from all mothers to evaluate the maternal immunoglobulin G (IgG) level. Blood samples were also taken from the baby’s umbilical cord during delivery to measure the newborn’s IgG level. Additionally, blood samples were collected from babies whose mothers showed signs of acute infection to measure their IgM levels and evaluate vertical transmission. Findings The study found a significant relationship between the mean level of maternal IgG and umbilical cord IgG within the groups (P
